  INTRODUCTIONS

This RMI9041 IP to ISDB-T modulator is a newly developed modulator, especially for applications of Japanese and South American applications of digital TV head-end. It is fully compliant with ARIB STD-831 standard and proved to be in high performance. RMI9041 is able to deal with 4*IP transport streams at the same time, each can be MPTS or SPTS, and unicast or multicast mode. IP port is configured with 1000M Ethernet interface, in UDP protocol. The device can output 4*IP in mirror of each input IP stream, and RF after processing of multiplexing. It is designed in output with two adjacent carriers for RF out, to make max. use of frequency resources.
Based on repeated tests, this RMI9041 modulator has been proved to perform in good parameters. It is a device quite suitable for digital TV head-end broadcasting, contribution and distribution applications.
